Title: Liquid spray method and apparatus having uniform dispersion amount distribution
Inventor: KUROSAWA ATSUSHI
IPC: B05B1/06
Filed: 1984-12-14
Abstract: PURPOSE:To perform spraying having uniform dispersion amount distribution, by forming a part of a liquid to be sprayed into a revolving stream and converting the other part thereof to a jet stream while flowing both streams into an outflow chamber to perform the exchange action of two kinetic energies. CONSTITUTION:A part of the liquid flowed into the inflow chamber in a main body 1 through an inflow port is flowed into an outflow chamber 6 through a revolving stream forming flow passage 4 outside a flow passage element 2 to be formed into a revolving stream. At the same time, the other part of the liquid is flowed into the center of the revolving stream in the outflow chamber 6 as a jet stream through the orifice 5 provided to the center part of an outflow element 2. At this time, the exchange action of periperal speed energy and axial speed energy is generated by the contact of the revolving stream and the jet stream in the outflow chamber 6 and the mixed stream formed by this energy exchange is injected into the open air from the nozzle 7 communicated with the outflow chamber 6.

Title: Manufacture of carbon for lithium ion secondary battery negative electrode
Inventor: OKAMURA KEIICHIRO
IPC: H01M4/587
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To efficiently and stably manufacture a carbon material of a prescribed grain size by pulverizing the carbide in the two-stage pulverizing process, i.e., a rough-pulverizing process and the fine pulverizing process, and achieving graphitization after the grain size has been adjusted. SOLUTION: Mesophase carbon fiber is preferable for the carbide because the capacity of the secondary battery is easily increased, and the mat-like carbon fiber is adopted from the relation between the spinning and the handling property. Because pulverization is achieved in the rough-pulverizing process and the fine-pulverizing state, the grain size can be adjusted easily, and the load on a pulverizing machine is reduced. A high-speed rotary mill is optimum for each pulverizing machine used for rough pulverization and fine pulverization. The grain size of the stuff to be pulverized is adjusted by mainly controlling the peripheral speed (number of revolutions) of a rotor and the air volume.  Rough pulverization is achieved at the peripheral speed of 80-140 m/sec, while fine pulverization is achieved at a peripheral speed of 105-150 m/sec in an efficient manner, and preferably the difference in the peripheral speed between the rough pulverization and fine pulverization is preferably 5-30 m/sec.

Title: Document summarizing device and computer-readable recording medium
Inventor: IKEUCHI HIROSHI
IPC: G06F17/27
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a document summarizing device which can obtain a high precision summary from a title and its body like a newspaper article. SOLUTION: A title extraction part 9 extracts the title and body from a document inputted from a document input part 1 and a document analysis part 5 decomposes the title into words and the body into sentences and words. A context vector generation part 6 generates the context vectors of the title and the sentences in the body. A context vector comparison part 7 compares the context vectors of the title and the respective sentences of the body with each other to calculate the distances between the context vectors. Sentences close to the title are generated and used as an important part of the document. Thus, the input document is analyzed by using the context vectors to extract the important part of good quality through an easy process without assuming a specific document form and a specific context.

Abstract: PURPOSE:To prevent a cutter body of a throw-away cutter such as a face milling cutter or the like, from chattering, by arranging such that the axial rake angle of the main cutting edges of a part of throw-away chips is different from that of the other. CONSTITUTION:Six throw-away chips 6 having the same shape and the same size are attached to the outer periphery of the front end part of a cutter body 5 through the intermediary of a supporter 7 by means of wedge members 8 and screws 9. Further, the inner peripheral side main cutting edges 10a, 10b of the tips 6a, 6b are alternately arranged such that they are separated radially in the rotating direction by X, Y from the diametrical lines L1, L2, respectively, while they are positioned on planes S1, S2 which are parallel with the axis O, and are inclined by gamma1 deg..
